description Provided are an apparatus and method for multiplexing and demultiplexing based on DMB. The multiplexing apparatus includes a packetizer, a section generator, and a multiplexer. The packetizer packetizes element streams and object information of a base layer and an enhancement layer. The section generator generates 14496 sections including the object information of the base layer and the enhancement layer, a SCST section having element stream information of the enhancement layer, an IOD having descriptors for the object information of the base layer and the enhancement layer, and a PSI section having a descriptor connecting the SCST.; The multiplexer generates base layer and enhancement layer TSs by multiplexing the packetized element streams and the packetized object information of the base layer and the enhancement layer, the 14496 sections including the object information of the base layer and the enhancement layer, the PSI section, and the SCST section.
